摘要： A system (and methods) for transferring multimedia information from a source location to a destination location through one or more networks, which may be different. The system has a source output which provides a first stream of information in a first format. The system also has a destination input which receives a second stream of information in a second format. A proxy transcoder server (“PTS”) is coupled between the source output and the destination input. The PTS has a transcoding module transcoding data. The PTS also has a capability module identifying a first capability of the source output and a second capability of the destination input, and selecting a transcoding process based upon the first capability and the second capability.

摘要： A method of reducing a call set-up time between a pair of H.324-like terminals coupled to one or more telecommunication networks includes providing a first capability identifier in at least one of a non-standard or generic field of a first TCS message, transmitting the first capability identifier from the first H.324-like terminal to the second H.324-like terminal, and receiving, at the first H.324-like terminal, a second capability identifier in at least one of a non-standard or generic field of a second TCS message transmitted from the second H.324-like terminal. The method also includes determining, at the first H.324-like terminal, a mode of operation by utilizing an inference algorithm based upon at least the first capability identifier and the second capability identifier. The method further includes transmitting media from the first H.324-like terminal to the second H.324-like terminal in accordance with the determined mode of operation.
